Check Digit Verification of cas no
The CAS Registry Mumber 208447-17-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,8,4,4 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 208447-17:
(8*2)+(7*0)+(6*8)+(5*4)+(4*4)+(3*7)+(2*1)+(1*7)=130
130 % 10 = 0
So 208447-17-0 is a valid CAS Registry Number.

Pd/Cu-catalyzed couplings of β-amino esters with aryl bromides. Synthesis of chiral 1,2,3,4-tetrahydro-4-oxo-2-alkyl-1-quinolines

A new protocol to prepare chiral 1,2,3,4-tetrahydro-4-oxo-2-alkyl-l- quinolines has been developed. The key steps are Pd/Cu-catalyzed couplings of chiral β-amino esters and aryl bromides, and intramolecular acylation.
